My invention has for its object a vehicle tire which 1s nir tight in Athat it-is adapted to retain a requisite internal au` pressure at all times without employment of the so called inner tube heretofore conventionally used.

My tire is Felt-halting' and of simple integral construction and may be mounted lor -demounted from the vehicle wheel with the greatest ense while securing reliability and.,

continuons operation to a most efiicient de- Igrec.

'Other advantages will be apparent from the chiawingrs and specications which follow.

heter-ringto the drawings Fig. 1 is a cross section on the line I- ot Fig. 2 ot' a tire employing my invention mounted on the rim of a conventional wheel, and in deflated condition, the wheel parts being shown somewhat diagrammatically.

Fig. :Z is a longitudinal .section partly on the line Vll-II and partly on the line llot Fig. 1.

Throughout the figures similar numerals refer to identical parts.

A main casingr is indicated by the numeral 1, having the tread 2, and bead portions 3, 4. and reinforcing; bands 5, G respectively, all ot' which are mounted in'a conventional manner upon the. rim 7 and felloeS of any conventional wheel.

lt is understood that the casing is built up ol rubber and canvas or other suitable impeiw'ious resilient material-in a conve- 'tional way and provided 'with n rubber lin iepr integral therewith. The casing is parted between the bead portions 3, 4 and a'ong this parting' joint provide the rubber or other flexible expansion member or flap 9 extending into engagement with and seating in the recess lt), formed inthe other side oi" the casing and sealing'- therewith under air pressure. n

These portions 9 and '10 are preferably formed integral with the asingr 1 and are made, el or provided with a relatively sott rubber or other suitable contacting' surfaces. At 11. is introduced a tongue or fibre or slumnmn or other non-rnstable material registering in the groove lor recess l2 to facilitcte ythe alignment of the portions 3, i andslsolgm prevent-dust, dirt and foreign matter from workingrup through the joint at 13 and damaging the contacting surfaces between 9 and 10.

At 14 is a conventional air tube containing the usual valve whereby air is admitted to the interior 18 ot the casinpr and the casing thereby inflated.

The inflation of the casing causes a heavy pressure inthe direction ot the arrow 19 against the flap 9 causing it to conta t air tight against the surface 1t). and enabling the tire to be inflated and retained in inflated condition.

The manner in which tlv`- tlap 9 seals against the surface l0 is shown c'ea-rly in Fig. 1.

It will now be seen that my invention provides a self-locking air tight, single tube tire of simplest, cheapest and most reliable construction.

This application is a division of mj; pendiner application, Serial 66.696, filed Nov. e,

I claim x-i I1. In a vehicle tire a casing having an inner lining ot impervious resilient niaterial inthe form ot' a holow annulus adapted to contain compressed air, with circumferential side locking members and a circumferential joint between said sidesp portions of said joint adapted to overlap and be held in air tight contact by air pressure within said annulus and a tongue in one of said portions and a groove in the other portion, said tongue and groove interengeginp; when said joint is closed.

2. In a vehicle tire a casing having; an inner lining of 'Publier or the like in the form of a hollow anniilus adaptedto contain compressed 'airfwith circumferential side locking members and a circumferential joint. between said sides,- portions of said joint adapted to overlap and be held in air tight contact by air pressure within said annulus, the contacting surface portions ot said joint faced with relatively sott rubber and posi-v tioned at onel side of a central 'plane through said annulus, an inlet tube and'valve there in to admit air to the hollenY annulus and retain said air compressed therein.
